Pumps as Turbines (PATs) are a family of unconventional reaction water turbines hydraulically similar to Francis units. Unlike conventional water turbines, water pumps are mass manufactured and available off-the-shelf in a large variety of sizes and types, besides being cost-effective and reliable.

Since the cost of purchasing the turbine+generator unit typically represents for hydro schemes in the "micro" scale (i.e. P < 100 kW) the majority of project costs, the adoption of PATs could make economically viable a large number of energy recovery sites in water infrastructures.

In order to validate the developed PAT sizing software, an experimental PAT testing facility has been built in the spaces of Simon Perry Building in Trinity College, Dublin.

Arbrofion mewn labordy o dyrbinau MHP newydd ar gyfer y farchnad

Teulu o dyrbinau dŵr adwaith anghonfensiynol yw Pympiau fel Tyrbinau (PAT) gyda systemau hydrolig tebyg i unedau Francis.  Yn wahanol i dyrbinau dŵr confensiynol, cynhyrchir y pympiau dŵr ar raddfa fawr ac maent ar gael mewn ystod eang o feintiau a math, yn ogystal â bod yn gost-effeithiol a dibynadwy.

Gan fod y gost o brynu’r uned tyrbin a’r generadur fel arfer yn addas i gynlluniau dŵr ar raddfa “micro” (h.y. P < 100 kW), gallai mabwysiadu PATs mewn nifer fawr o safleoedd adfer ynni mewn seilwaith dŵr fod yn hyfyw yn economaidd.

Er mwyn dilysu’r feddalwedd i amcangyfrif maint PAT, adeiladwyd cyfleuster profi PAT arbrofol yn Adeilad Simon Perry yng Ngholeg y Drindod, Dulyn.
